How do you prevent galling on stainless steel bolts?

Lubrication is an important way to reduce galling by allowing the two materials to slide past each other without causing friction. Some leading premium fastener manufacturers use custom-made wax to ensure an optimal friction coefficient. Anti-seizing and anti-galling lubricants can also help reduce galling.

Why do stainless bolts gall?

Friction causes galling, so any form of interference or heat build-up can cause galling. Common triggers are debris in the thread, reusing overtightened hardware, and threading soft materials together such as stainless steel. Another common trigger is damaged threads due to shipping.

How do you keep stainless steel threads from binding?

Lubricate the threads.

Can you use anti-seize on stainless steel?

Featuring excellent lubricity in these challenging environments, marine grade anti-seize lubricants prevent galvanic corrosion in both fresh and salt water, with a broad range of temperature resistance preventing seizure of aluminum, steel, stainless steel, and soft metals.

Why do stainless steel bolts seize?

While the fastener is being tightened, pressure builds between the thread surfaces and breaks down the protective oxide coatings. Without the oxide coating, the thread’s metal high points are exposed to each other. This, in turn, creates friction, which causes heat that seizes the metal.

Why does stainless steel seize?

Galling is often referred to as cold welding. In the case of stainless steel fasteners, it occurs when oxidized film from the stainless steel is broken or wiped away by pressure. During the tightening process, high levels of pressure actually remove that film on the threads of both the bolt and the nut.
